Link update in InDesign CS4 JS

Question

Hi, I need some help. This loop use to work, but know it's giving me an error, and when I added the alert I see that it's giving me only first letter of the file's name. Could you help me to find out what happened.
for (var a =0; a<app.activeDocument.rectangles.length-1; a++){
myArt = app.activeDocument.rectangles[a].graphics[0];
myArtName = myArt.itemLink.name[0];
alert (myArtName);
myArt.itemLink.update (myArtName);
Thank you very much.

Thank you, Ramkumar.
That helped. Now I am stuck on the next thing. It updates the broken link, but gives me an error when link is good. So I am trying to figure out an IF statement, so it only updates broken links. Here what I've tried and none of it works:
for (var a =0; a<app.activeDocument.rectangles.length-1; a++){
myArt = app.activeDocument.rectangles[a].graphics[0];
myArtName = myArt.itemLink.name;
var myLink = myArt.itemLink;
    if (myLink.edited = true)
    myArt.itemLink.update (myArtName)
or
for (var a =0; a<app.activeDocument.rectangles.length-1; a++){
myArt = app.activeDocument.rectangles[a].graphics[0];
myArtName = myArt.itemLink.name;
if (myArt.itemLink.edited = true)
    myArt.itemLink.update (myArtName);
or
for (var a =0; a<app.activeDocument.rectangles.length-1; a++){
myArt = app.activeDocument.rectangles[a].graphics[0];
myArtName = myArt.itemLink.name;
if (myArt.itemLink.linkStatus = LINK_OUT_OF_DATE)
     myArt.itemLink.update (myArtName);
Thank you so much for your help.
